string.maketrans().lower()

[Hallvard B Furuseth]

I have a translation table from
tr = string.maketrans(...)
and want a table which produces the same characters lowercased.

`tr.lower()' works - at least with Python 2.3 - but is that will
that remain reliable? Or should I use something like this?

string.maketrans("".join(map(chr, xrange(256))),
"".join(map(chr, xrange(256))).translate(tr).lower())

BTW, is there a simpler way to write "".join(map(chr, xrange(256)))?

Sure. The return value of string.maketrans is just itself a string,
after all.

You could use a list comprehension if you prefer.

Not 256 chars, but some of them where lower and upper really makes sense.

import string
string.ascii_lowercase 'abcdefghijklmnopqrstuvwxyz' string.ascii_uppercase 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'

Thanks.

map() looks clearer to me in this case.
